Ore shoots steepen towards the Shear Zone (Oliver et aI., 1999). A lack of garnet and uranium mineralisation in the shear adjacent to the Mary Kathleen open cut suggests that the normal faulting postdates ore formation, and hence postdates intrusion of the .

RADIOMETRIC SORTING REPORTS POSITIVE RESULTS

RADIOMETRIC SORTING Radiometric sorting is a simple technique that uses the primary physical characteristic of the ore (radioactivity due to the presence of uranium) to divide the sample into two portions: a radioactive portion (the accept fraction) and a non‐radioactive portion (the reject fraction).

Radiometric sorting in uranium processing cuts costs ...

"Radiometric sorting separates uranium ore from the waste rock, producing a uranium-rich beneficiated ore for subsequent processing in the hydrometallurgical circuit. While it reduces the load of downstream processing, it also makes the downstream operations more economically viable with reduction in plant capital and operating costs.

Jan 01, 2016· Radiometric sorting trials at Ranger mine in Australia and Rössing in Namibia are reported by Schnell (2014), who also comments that "[G]ravity separation has been applied to uranium ores in the past with some success, but this was associated with radiation issues" (cf. Section 6.5.1, where it was used with very high-grade ore).

Uranium–lead dating - Wikipedia

Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range.

Uranium Mining Overview - World Nuclear Association

This may be radiometric sorting as at Ranger, screening/gravity, or a new process called ablation. Most of the ore is barren rock or other minerals which remain undissolved in the leaching process. These solids or 'tailings' are separated from the uranium-rich solution, usually by allowing them to settle out.
